We study the role of dark and bright autoionizing states (AISs) in photoionization and high-
order harmonic generation (HHG) using a one-dimensional helium model. This model …

A precise understanding of mechanisms governing the dynamics of electrons in atoms and
molecules subjected to intense laser fields has a key importance for the description of …

An ab initio analysis of strong-field three-electron ionization in a restricted-dimensionality
model reveals the dynamics of the ionization process and the dominant channels for double …

We present an ab initio study of the nonsequential strong-field ionization dynamics of a
model two-electron atom with helium character. Single-and double-ionization events are …

We present results on the accurate one-dimensional (1D) modeling of simple atomic and
molecular systems excited by strong laser fields. We use atomic model potentials that we …

The full-dimensional quantum mechanical description of double ionization in strong laser
fields is still computationally very demanding. We demonstrate the versatility of a simplified …

We present a joint experimental and theoretical study of non-sequential double ionization
(NSDI) in argon driven by a 3100 nm laser source. The correlated photoelectron momentum …

We study strong-field double ionization in a three-electron atom by applying a simplified,
reduced-dimensionality model with three active electrons. The influence of the spin-induced …

The interaction of strong pulsed femtosecond laser field with atoms having three equivalent
electrons in the outer shell (p 3 configuration, eg nitrogen) is studied via numerical …
